I did not receive the cross-post so I will respond here for now.

Is the L1 sysadmin the only target audience here? Does LPI also cover
technical support professionals and system engineers? I could not find
any reference to the target audience on the LPI web site other than
the Job Analysis Survey.

The major and minor numbers are important, from my perspective, when you
are dealing with hardware that requires device files that are not in the
MAKEDEV script. Since this is likely to be an issue at installation time,
it is likely relevant to L1. In addition, knowing how to identify devices
based on error messages from the kernel is important for troubleshooting
purposes.
However, until I have a concrete understanding of the target audience,
I cannot say whether this should be L1 or L2. Based on installation
issues with hardware, I would recommend adding it to L1.

I use the unstable tree of Debian. It appears to have added the procinfo
package:
###
apt-cache search --full lsdev
Package: procinfo
Priority: optional
Section: admin
Installed-Size: 108
Maintainer: Chip Salzenberg <[EMAIL PROTECTED]>
Architecture: i386
Version: 17-1
Depends: perl5, libc6 (>= 2.1), libncurses5
Filename: dists/woody/main/binary-i386/admin/procinfo_17-1.deb
Size: 20604
MD5sum: 9a27fdf66a107d00060241fb810111b8
Description: Gathers and displays misc. system information.
The procinfo command gets miscellaneous system data from the /proc
directory (the kernel filesystem), formats it, and displays it on
standard output.
.
The lsdev command uses /proc to displays a best guess of the I/O
ports and interrupts used by active hardware drivers.
.
The socklist command uses /proc to display a list of open sockets.
